IMPROVEMENT IN FINISHING WOOD.

TO ALL WHOM IT MAY CONCERN: I

Be it known that I, GEORGE CHAMBERS, of Ithaca, Tompkins county, N ew York, have invented-an Improved Preparation for and Mode of Finishing Wood; and I do hereby declare that the following is a full and exact description thereof. p y v My object is to produce a hard and glazy suri'aee, cheaply, durable, and rapidly on the surface of Wood.

For this purpose, I make a preparation asfollows To any convenient quantity of boiled linseed oil I add, over'and above the ordinary drying-use of the article, any free and largefexcessof litharge, and also a small quantity of chalk, "or of chalk and whiting anrlstarchL- .This makes a thick, glutinous semi-fluid mass. Next,

the surface of the wood being eut, -planed', or sand papered, or otherwise smoothed andpolished, but having no preparation or mixture of any kind o n'it,I coat it over .with the above preparation, rubbing it freely into the pores and'graiuof the wood.-, Then I at once apply a thick dusting orcoating'over the wood thus coveredwith my. preparation of sulphate of lime or plaster of Paris. I let it stand for a few moments, that the fluid parts of the oil may be absorbed by the sulphate of liine. Then I proceed at once and polish .the surface, using, if

necessary, more plaster of Paris in so doing. Brushes, woollen cloths, and other articles in rubbing and polishing, are useful and used. Further, to suit the color of the wood, I use in my preparation, and inthe plaster of Paris, .various coloring-substances, the mineral ores being especially useful, as Vandyke brown, umber, Spanish yellow for black walnut and oak, chalk'and whiting (in additional quantities) for maple and cucumberand-satinwood, and so ofotheroolors and woods. These I mix in the preparation before it is applied to the \tood, and, if necessary, in the plaster oi' Paris in polishing. The result is a fine, clear, even polish, that hardens, and is dry and ready for use, in much shorter time than varnish or other ordinary articles and modes. The use of my invention is apparent to those skilled in the art to which it appertainsn Claim. The preparation made of the ingredients and colors, and used substantially in the manner and for the purposes specified.

GEORGE CHAMBERS.
